# Percents API

The Percents API lets issuers integrate card linked offers, cashback, and branded rewards. Branded balance is merchant-scoped value that a cardholder earns with a merchant and can later spend at that merchant when the balance is available and eligible.

Use `https://sandbox.percents.com` for testing. Production uses `https://prod.percents.com`.

Start with the [Integration Path](/percents-api/overview/guided-overview) for the issuer workflow, or go directly to the [API Reference](/percents-api/openapi/percents-api) when you are ready to implement.
